Johnson's Auto-Lock™ tape measures are easy to read, lock and operate. These tape measure feature a 1" Auto-Lock™ blade that self-locks and can be retracted at the push of a button. The Speed-Read™ blade was designed for easy viewing, with fractional graduations every 1/8", while the Tiger Claw™ 4-rivet blade hook keeps the blade from slipping. For durability, the Blade-Gard™ nylon-coated blade resists abrasion while the ergonomic co-molded rubberized case is impact resistant.
